SIP Trunking

Get access to new markets. Add new features to your PBX. Save costs on international calling.
SIP Trunking

Expand Your Telephony Coverage

Some telecom providers don’t allow you to make calls in regions you want to expand to or they may charge excessively. With SIP Trunking, you can easily build a bridge between your PBX and the Voximplant cloud to make phone calls to 190+ countries.

Bring New Functionality to Your PBX

Some PBXs are not flexible enough to build complex communications apps such as IVRs, voicebots, VMDs, and call centers. If you want to add new features to your PBX, you can embed Voximplant Platform into your infrastructure to process complex scenarios.

Automate Customer Communications

For instance, Voximplant Platform allows you to build Smart IVRs to automatically handle and route inbound customer calls to your agents. In this case, SIP trunks will transfer customer calls from your PBX to our cloud and then to agents.
